This invention relates to ar vehicle,` particularly a vehicle in theform of afs-led fhavf.

ing runnersadapted tol move about axes-.extending longitudinally ofthesled. I As "is i well known, it isf often desirable: to.' make turnswith 'the' Vsled* whileth'e same .is in rmotion. Difficulty is oftenexperienced inzmaking turns and -sledsor sleighs oftenover# turn atvsucl'ijtimes.y Y Itfis 1an object of the .invention to 'provide a'sledor sleigh having runners'` with 'conn parativel'y sharpbott/oimrunners,l whichrunners: are adapted -tobe moved aboutlongitudinal'axesto cause said runners orv the cor- 15 ners thereof tobe inclined tothe rsupporting surface' so that-'a 'much' greaterresistance will be offered to the runners and the skid- 'ding movementof the sled' will be prevent-ed and lthe turning thereof' jfacilitated.

It is a furthervobj'ect `ofthe{ir-iventio'n` Vto provide asl'edgor-sleigh havingspaced runners, together `with means for.ysimultaneousl'yl turning said' runners abo'utaxes ex-'V tendinglongitudinally of the sled;

jThese and'v otherobjects "and 'advantages of theinvention-will be fullyset forthfin the following description madel inconnection with theaccompanying drawings in which like' reference- "clharacte'rs refer tothe same parts th'roug-houtfthe di'erent views, 'and in which, f f "l'f' Fig. 1 'is 'Ya view in side' elevationof the sl'ed-t embodying-*theinvention ;f

Referring to the drawings, a sled is shown comprising a frame or bodyhaving a seat board 6. Secured to the board 6 are spaced transverselyextending bars 7 having ldownturned ends forming bearings and supportsfor the parallel sides of a rod 8 extending longitudinally of the board6 beneath the same and across the front end thereof. While the rod 8 mayloe made in various forms, the same is illustrated as formed of 5 5ordinary piping. The rod 8 is firmly and l cylindrical "'ro *13;v extenaigdiy lrelu in the. bars 7.- spacea runners y9 are provided,andlwhilethese' runners may be 'made various: ferme,- in ther euiib'oel4ment -of the' invention illustrated, the l' -sam'e are-shown -as in theforniy 'of angle fbars hav@ ing sides* y'exten'din-g'substantially v*atright 'angles 'I withv 'comparativelyp` sharp corners which aredisposed-outwardly of" gsaid' 'sled The-runners Qfhave barslO's'ecuredthereto, theV ends of which ex'tenjd upwardly, as indi-icated atv 10?,having apertures adjacent their upper ends throughwhichf passfthe'ro'ds8.

The disk 14 has links 15 pivotally secured at each side ofthe longitudinal axis of the board 6, which links extend outwardly andare also pivotally secured to the forward bar 11. The stem 13 has anoperating hand wheel 16 secured at Vits upper end some distance abovethe board 6. y Y Y v i In operation, the sled will be drawn `or willmove down an incline by gravity in the usual manner. If it is desired tomake a turn with the sled, the wheel 16 will be turned and, through thecrank disk 14 and links 15, the bars 11 will be moved to swing therunners 9 about the axis of the side rod 105 8. If the'turn is to bemade to-ward the left the runners will be turned, as shown in Fi 3. Thefiat bottom side of the runnerls turned at an angle and the sharp cornerof the runner is brought into engagement with 110 so. y

parts without departing applicantl has the surface of the snow or iceand will bite into the surface so that the sled is turned,

and side slipping and skidding of the sled prevented.v If the supportingsurface is slightly soft the fiat bottom of the runner ner of the runnerinto engagementl with the surface also increases the lateral resistancevwhich causes the sled-to turn, the same way f that 'a skate is turnedwhen the skater makes a turn on the ice, or inthe same manner that askier'turns his skis.- The sled vnaturally turns away from the sideencountering said lateral resistance. Side slipping or skidding of thesled and consequent overturning, is avoided and a firm lateral thrust orbearing against the supporting surface is obtained. If the turn is to bemade in the other direction, the runners will, of course, be turned inthe opposite direction.

From the above description it is seen that provided a simple andeficient sled structure for effectively turning the sled and preventingskidding on curves, thus greatly facilitating the control of the sled inturning curves. The device has been amply demonstrated in actualpractice and found tobe very successful and eiiicient.

It will, .of course, be understood, that various changes may be ma-de inthe form, details, arrangement and proportions of the of applicantsinvention, which, generally stated, consists in a device capable ofcarryingrout the objects above set forth, in the novel parts andcombinations of parts disclosed and defined `in the appended claims.

Y What is claimed is:

l. A sled having in combination, a frame comprislng a seat, lugs rigid.with respect to" said seat and disposed close thereto at each side ofand beneath the same, arms pivoted at their upperends to saidlugs aboutthe turning from the scope gle directed outwardly, means connected toVsaid arms between said runners and lugs for swinging said arms laterallyabout their `pivots and operating mea-ns for said last mentioned means.

2. A sled having in combination, a frame comprising a seat, lugs rigidwithrespect to said seat and exten-ding downward a short distance ateach side thereof, arms pivoted at their upper ends to said lugs andnormally extending vertically downward therefrom, a pair of runners'rigidly Vsecured to the lower ends of said arms and disposedrespectively at each side of saidframe, said runners being of angleshape in cross/.section, `with the angle directed outwardly, a crankdisk mounted below said frame, means connected to said diskv and tolsaid arms between said runners and lugs, a stem connected to said diskand extending above said Vframe and seat, and an operating memberconnected to the upper end of said stem to turn the same and swing saidarms and runners about the pivots of said arms. Y Y f 3. A sled havingin, combination, a seat, spaced rods extending longitudinallytherebeneath, spaced runners mountedV on said rods for lateral swingingmovement,a1ro tatable vertical stem extending through said seat, a crankdisc at the lower .end thereof, means connected to said crank disc andsaid runners Y for simultaneously 'turning them in the same directionabout said rods, and means secured to said'stem above said seat forturning said stem and disc.
